I have been struggling with setting up Carrot2 for use PHP, on a local machine. The plan is to have Carrot2 retrieve cluster from Solr populated by Nutch. Currently Solr and Nutch are correctly configured and I have been able to access the information via Carrot2 Workbench. Carrot2-dcs-3.10.0 has been set up what I believed to be correctly deployed through the tomcat6 manager although the documentation on setting this up is horrible vague and incomplete. Changes to source-solr-attributes.xml were made according to https://sites.google.com/site/profileswapnilkulkarni/tech-talk/howtoconfigureandruncarrot2webapplicationwithsolrdocumentsource . Tomcat is set up on port 8080. The Carrot2 DCS php example example.php works and displays the test output correctly. Although, when I try to perform a cluster using localIPAddress:8080/carrot2-dcs/index.html I run into a problem. When I set document source to Solr and the query to : then click cluster I get the following error message.
HTTP Status 500 - Could not perform processing: org.apache.http.conn.HttpHostConnectException: Connection to localhost:8983 refusedtype Status report
message Could not perform processing: org.apache.http.conn.HttpHostConnectException: Connection to localhost:8983 refused
description The server encountered an internal error that prevented it from fulfilling this request.
I have searched everywhere in the deployed webapp folder for carrot2 and can't find where it is getting localhost:8983 from.
Any assistance would be appreciated, thank you.
It turns out that the source-solr-attributes.xml file had an extra overridden-attributes. one was before the default block comment with the example parameters and the second was added in by me with the parameters needed for my config. Deleting one of the line so there was only one corrected the problem. Apparently with two of those it ignores the server settings and uses default values instead.
